Sharpness at 50mm

For these tests, the Olympus 12-50mm f3.5-6.3 lens was attached to an Olympus E-P3 compact system camera, which in turn was mounted on a sturdy tripod. The self-timer was used to avoid any vibrations from pressing the shutter release. Slight tonal changes are due to slight changes in natural light during the session. The 100% crops represent about 1/300th of the total frame area.
